Three pedestrians were struck in two separate collisions on Saturday, and all have been left fighting for their lives. Thus far, neither of the drivers have been cited by the San Francisco Police Department, but one of the pedestrians has.

In the first case, a 20-year-old motorcyclist on a 2008 Aprilia was heading south on Van Ness when he allegedly struck a 44-year-old man near Myrtle Street (that's the small alley next to the 1000 Van Ness movie theatre).

The pedestrian was taken to San Francisco General Hospital with life-threatening injuries, including a broken leg, a fractured pelvis and severe head trauma, SFPD spokesperson Officer Albie Esparza told SFist.

The motorcyclist complained of pain to his wrist, as a result of the collision, Esparza said.

As the "cause of the collision"—the pedestrian, Esparza emphasized, was not crossing at an intersection, and was "in the middle of the street,"—the injured pedestrian has been cited by SFPD for failing to be in a crosswalk.

In a separate incident, on Saturday afternoon at around 4:30, a 40-year-old man was parking near Grant Avenue and Chestnut Street. According to police, he thought he had put his gray four-door 2013 Acura into park, but when he lifted his foot off the brake, he drove into the sidewalk and allegedly struck a 3-year-old boy and a 75-year-old man.

The driver remained at the scene and cooperated with police, but was not cited.

"That collision is still under investigation," Esparza said, so a citation could still be issued, depending on what's decided by the investigating officers.

After the collision, both the adult and child were rushed to SF General Hospital with life-threatening injuries to their head and chest. An update to their condition was not available at publication time.
